CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on May 7, 2013 in the Korean Intellectual Property Office and assigned Serial No. 10-2013-0051185, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a transmission of content. More particularly, the present disclosure relates to an apparatus and method for transmitting and sharing content using a wireless communication scheme, which can be more conveniently used and is capable of minimizing a consumption of electric power.

BACKGROUND

A portable terminal which is provided to a user in a form of a smart phone, a tablet PC and the like has provided various useful functions.

The portable terminal has included various kinds of communication modules, i.e. a long-range communication module supporting 3G/4G communications and the like, and a short-range communication module supporting Wi-Fi communication and the like, to provide various wireless communication techniques. For example, the portable terminal can perform data communication including data sharing with other portable terminals using the communication modules. However, data communication techniques have not provided a user with convenience during the data communication such as during data sharing because of various reasons now described.

When transmitting a file using communication techniques of the related art, a file to be transmitted is first selected, a transmission button is pressed, and potential recipients of the file are listed. A recipient is selected from the list, and a process of certifying the recipient is completed. When an apparatus corresponding to the recipient stays in a standby state capable of receiving the file, the file transmission starts. Accordingly, the process is very complicated and inconvenient.

Also, many users are not familiar with wireless transmission techniques such as Bluetooth, Wi-Fi Direct, Digital Living Network Alliance (DLNA), and the like. Further, users have difficulty in learning new technical features such as searching, scanning, pairing, bonding, Wi-Fi Protected Setup (WPS), Secure Simple Pairing (SSP), visibility, Discoverable, and the like. Accordingly, users cannot easily choose which wireless transmission technique is suitable for file transmission under certain circumstances. Therefore, it is problematic that a user transmits or receives a file using only wireless transmission techniques with which the user is familiar.

Further, in a case of sharing a file using a wireless transmission technique such as Bluetooth (ver. 3.0 or earlier) and Wi-Fi, either a Bluetooth module or a Wi-Fi module of the apparatus for transmitting and receiving the file must be active. Accordingly, where the apparatus is a portable terminal that is battery-operated, continuous consumption of electric power by the Bluetooth module or the Wi-Fi module is a problem. For example, since the activation of the Bluetooth module or the Wi-Fi module for data communication causes a significant consumption of standby electric current, portable terminals such as a smart phones or a tablet PC can be inefficient. Further, in a wireless transmission technique such as Bluetooth or Wi-Fi, there is a problem in that it sometimes takes several tens of seconds, for example thirty seconds, of scanning to identify an object that is to receive the file.

In order to address the above-mentioned inconveniences, a technique of transmitting data after performing Out Of Band (OOB) pairing using Near Field Communication (NFC) and the like is utilized. However, this technique results in an increase in power consumption in a data receiving apparatus since the data receiving apparatus must continuously remain in a standby state in order to receive data.

Accordingly, there is a need for an improved apparatus and method for transmitting and sharing content using a wireless communication scheme, which can be more conveniently used and is capable of minimizing a consumption of electric power.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

A short-range communication module 40 provides a short-range wireless communication function.

The short-range communication module 40 according to various embodiments of the present disclosure may include a plurality of communication modules such as a Bluetooth module, a BLE module, a Wi-Fi module, and the like. The short-range communication module 40 according to an embodiment of the present disclosure may include an Infrared Data Association (IrDA) module, a Near Field Communication (NFC) module, a ZIGBEE module, an ANT module, and an RFID module. Referring to FIG. 1, the short-range communication module 40 is shown including one antenna. However, the short-range communication module 40 may include a number of antennas corresponding to the number of communication modules.

Alternatively, the BLE module may be a short-range communication module consistent with Bluetooth 4.0, and operates in a low energy mode compared to the Bluetooth modules of version 3.0 or earlier. The BLE module has a feature of minimizing battery consumption of a portable terminal even though it is continuously activated, and may be provided along with or as a substitute for the traditional Bluetooth module of version 3.0 or earlier.

Moreover, the BLE module may be associated with the controller 10 to broadcast advertising data including status information of the portable terminal, for example, a portable terminal of a transmitter and a portable terminal of a receiver. The BLE module is described in more detail in the following paragraphs.

The display unit 50 includes a Liquid Crystal Display (LCD) or an Organic Light Emitting Diode (OLED) and outputs various pieces of display information generated in the portable terminal. The display unit 50 may include an electrostatic touch screen, a resistive touch screen and the like, through which a user uses only the touch screen 50, or the touch screen 50 and the key input unit 40 together to operate the portable terminal, for example, in a manner of touching buttons.

The controller 10 controls overall operations of the portable terminal according to various embodiments of the present disclosure, and converts and controls the operation of the portable terminal according to a user input through the key input unit 27 or the display unit 50. Alternatively, the controller 10 according to an embodiment of the present disclosure controls the overall operations of a portable terminal at a transmitter side, or the overall operations of a portable terminal at a receiver side with respect to the performance of a content transmission method in the portable terminal. For example, the controller 10 according to an embodiment of the present disclosure controls a series of operations relating to the performance of the content transmission method in the portable terminal The content transmission method includes the enabling a portable terminal of a transmitter to be connected with a portable terminal of a receiver for a control communication when the portable terminal of the transmitter is requested to transmit content, allowing the portable terminal of the transmitter to select a type of data transmission communication with the portable terminal of the receiver through the control communication, allowing the portable terminal of the transmitter to transmit setting data corresponding to the selected type of data transmission communication to the portable terminal of the receiver through the connected control communication, enabling the portable terminal of the receiver to change a setting thereof corresponding to the selected type of data transmission communication, and allowing the portable terminal of the transmitter to be connected to the portable terminal of the receiver for the selected data transmission communication, so as to transmit the requested content to the portable terminal of the receiver through the data transmission communication.

Alternatively, although devices such as a camera module and a Digital Media Broadcasting (DMB) receiver which may be included in the portable terminal are not shown in FIG. 1, it will be obvious to a person of ordinary skill in the art that the devices (not shown) also are included in the portable terminal according to various embodiments of the present disclosure to provide corresponding functions. For example, in an embodiment of the present disclosure, the content shared (transmitted to and received from) with the portable terminal of the transmitter and the portable terminal of the receiver may be stationary images or video files taken by the camera module, or broadcasting video files which are recorded using the DMB receiver.

FIG. 2 is a flowchart illustrating a process of transmitting content according to an embodiment of the present disclosure.

FIG. 3A is a view illustrating a first example of an advertising data format which is broadcast from the portable terminal according to an embodiment of the present disclosure. FIG. 3B is a view illustrating a second example of an advertising data format which is broadcast from the portable terminal according to an embodiment of the present disclosure. FIG. 3C is a view illustrating a process of transmitting content according to an embodiment of the present disclosure. FIGS. 3D and 3E are views illustrating examples of a format of setting data transmitted in the process of transmitting content according to an embodiment of the present disclosure. Various embodiments of the present disclosure will be described with reference to the drawings.

Although the portable terminal, for example, the portable terminal of the transmitter and the portable terminal of the receiver, is described as one structural element for the convenience of this description, it will be obvious to a person of ordinary skill in the art that the primary operation is the controller 10 of the portable terminal and structural elements included in the portable terminal that are subject to instructions of the controller. Further, although the portable terminal of the transmitter and the portable terminal of the receiver are distinguished and described with relation to files for the convenience of the description, it will be obvious to a person of ordinary skill in the art that the portable terminal of the transmitter also can perform the operation of the portable terminal of the receiver, and on the contrary, the portable terminal of the receiver also can perform the operation of the portable terminal of the transmitter.

At operations S201 and S202, the portable terminal of the transmitter identifies that a user has requested the portable terminal to transmit desired content, and receives advertising data which is broadcast from the portable terminal

When receiving a request of the content transmission from the user, for example, a request of sharing content with the portable terminal of the receiver, the portable terminal of the transmitter activates the BLE module which is a low-energy short-range communication module so as to receive the advertising data which is broadcast from the other portable terminals including the portable terminal of the receiver.

Various embodiments of the present disclosure utilize the advertising data of the BLE module with a low-energy attrition rate. Therefore, the portable terminals, for example the portable terminal of the transmitter and the portable terminal of the receiver, according to an embodiment of the present disclosure broadcast the advertising data through the BLE module which is a low-energy short-range communication module. Therefore, the companion portable terminal receiving the advertising data can obtain status information of the portable terminal

The portable terminal according to an embodiment of the present disclosure stores the status information of itself in detail data of the advertising data to broadcast it, for example, in an AD structure 1 to an AD structure N. The advertising data and the status information will be described with reference to FIGS. 3A and 3B.

Referring to FIG. 3A, the maximum size of the advertising data provided in the BLE is 31 bytes, and the status information of the portable terminal is included in a plurality of the detail data, for example the AD structure 1 to the AD structure N, and can be broadcast.

Referring to FIG. 3B, even though the many pieces of information are included in the detail data of the advertising data, the embodiment of the present disclosure utilizes data corresponding to an AD type such as a TX power level, a shortened local name, a random target address, a manufacturer specific data <<protocol>>, a manufacturer specific data <<capability>>, a manufacturer specific data <<others>>, and the like, among the many pieces of information.

Here, the status information includes information on whether a communication status of the BLE module of the portable terminal is preferred, which wireless communication function is supported by using which protocol, a current operation mode, and the like.

For example, the portable terminal of the receiver (or the portable terminal of the transmitter) broadcasts information on an electric field, i.e. RSSI, of the BLE module through the data having the AD type of the TX power level.

Further, the portable terminal of the receiver (or the portable terminal of the transmitter) broadcasts information on device names through data having the AD type of the shortened local name.

Further, the portable terminal of the receiver (or the portable terminal of the transmitter) broadcasts a predetermined address such as Samsung Mobile or Starbucks through data having the AD type of a random target address. The data of the random target address is utilized in an application of a white list described later as well as in an address for a connection of the BLE communication.

Further, the portable terminal of the receiver (or the portable terminal of the transmitter) broadcasts information on an identification of a manufacturer, e.g., Samsung Electronics Co., Ltd., or information on a communication protocol, e.g., SSIP 1.0, through data having the AD type of a manufacturer specific data <<protocol>>.

In addition, the portable terminal of the receiver (or the portable terminal of the transmitter) broadcasts information on supported wireless communications among a plurality of wireless communications listed by 01 to 13, and also broadcasts information on usable sensors among a plurality of sensitive sensors listed by 14 to 20, through data having the AD type of a manufacturer specific data <<capability>>.

For example, when the advertising data in which information of AD data having 0x0000FF is stored in the AD type of the manufacturer specific data <<capability>> is broadcast, it is possible to inform that the wireless communications functions including (01) Bluetooth BR/EDR, (02) Bluetooth AMP, (03) Bluetooth LE (BLE), (04) Wi-Fi, (05) Wi-Fi Direct, (06) Wi-Fi Display, (07) DLNA (all-share) and (08) NFC, RFID, may be supported.

Furthermore, the portable terminal of the receiver (or the portable terminal of the transmitter) broadcasts information on an operation mode of the portable terminal, e.g., a silent mode, a screen rotation mode, a power saving mode, a notification mode, a mobile data transmission/reception mode, a driving mode, a sync mode, and the like, through data having the AD type of a manufacturer specification data <<others>>.

Alternatively, because the advertising data has the maximum size of 31 bytes, information on the shortened local name having the maximum size of 31 bytes may not be included in the advertising data in an embodiment of the present disclosure. For example, the advertising data is generated by using data corresponding to the AD types of the TX power level having a size of 1 byte, the random target address having a size of 6 bytes, the manufacturer specific data <<protocol>> having a size of 4 bytes, the manufacturer specific data <<capability>> having a size of 3 bytes, and the manufacturer specific data <<others>>.

At this time, the portable terminal which receives the broadcasted advertising data requests the portable terminal which broadcasts the advertising data, to transmit information having the AD type of the shortened local name which is not included in the advertising data due to the size thereof, and obtains the information.

For example, an apparatus, i.e. the portable terminal of the receiver, that broadcasts the advertising data sets the information on the shortened local name as data to be transmitted in response to a scan (scan_RSP) when the advertising data is generated. Then, in a case where the received advertising data lacks necessary status information, an apparatus, i.e. the portable terminal of the transmitter, which receives the broadcast advertising data, requests an advertising data including the necessary status information, i.e. shortened local name, by using the same advertising channel through an additional request (scan_REQ) at operation S203, and receives the advertising data including the necessary information through the respond (scan_RSP).

Furthermore, even though the controller of the portable terminal of the receiver enters a sleep mode, the portable terminal of the receiver (or the BLE module of the portable terminal of the transmitter) broadcasts the advertising data at a predetermined period, and responds to the scanning of the portable terminal of the transmitter. At this time, according to whether the controller enters the sleep mode, a period in which the advertising data is broadcast may be variable.

At operations S203 to S205, the portable terminal of the transmitter performs a scanning using the BLE module and displays detected apparatuses. Then, when a user selects an apparatus to which the content is transmitted, the portable terminal of the transmitter connects the BLE communication.

In an embodiment of the present disclosure, the portable terminal of the transmitter can perform the scanning by using the BLE module when the user requests the portable terminal of the transmitter to transmit the content, or when the advertising data which is broadcast by another portable terminal, i.e. the portable terminal of the receiver.

At this time, the portable terminal of the transmitter can scan the neighboring portable terminal of the receiver, i.e. an advertiser broadcasting the advertising data, by using scanning parameters indicated in Table 1 below.

TABLE 1 Set Scan Command parameters Definition LE_Scan_Type (0x00) Passive Scanning (default) (0x01) Active scanning (SCAN_REQ) LE_Scan_Interval Range: 2.5 ms~10.24 s (Default 10 ms) LE_Scan_Window Range: 2.5 ms~10.24 s (Default 10 ms) Own_Address_Type Public(default) or Random Target Address Scanning_Filter_Policy (0x00) Accept all advertisement packets (default). (0x01) Ignore advertisement packets from devices not in the White List Only.

The portable terminal of the transmitter displays to a user a list of one or more apparatuses which are scanned and detected by the BLE module and receives a user's selection for an apparatus to which the content are to be transmitted, so as to connect the BLE communication with the apparatus selected by the user. At this time, the portable terminal of the transmitter according to an embodiment of the present disclosure may selectively display a list of apparatuses satisfying the RSSI in a certain range, when a list of the apparatuses scanned and detected by the BLE module is displayed.

Referring to FIG. 3C, when only one apparatus is scanned and detected by the BLE module, assuming that it is the portable terminal of the receiver to which the portable terminal of the transmitter transmits the content, indicated by a reference numeral 311 on a display screen 310, the portable terminal of the transmitter connects the BLE communication with the apparatus, i.e., the portable terminal of the receiver, which is selected by the user, by inputting a touch input for a menu indicated by 311.

As shown in a display screen 320, when a plurality of apparatuses 321, 322, and 323 are detected as a result of scanning by using the BLE module, the user can sequentially select the plural apparatuses 321, 322 and 323, and the BLE communication is sequentially connected with the plurality of selected apparatuses so that the BLE communication of 1:N can be performed.

Here, since the portable terminal of the transmitter can broadcast the advertising, like the portable terminal of the receiver, it is assumed that the portable terminal of the transmitter temporarily stops broadcasting the advertising data when the advertising data is received from the portable terminal of the receiver, and performs the scanning.

Further, the portable terminal of the transmitter displays a list of only apparatuses having an RSSI value in a certain range, among the scanned apparatuses. That is, the portable terminal of the transmitter displays the minimal number of apparatuses, thereby improving the convenience with which the user selects an apparatus.

In an embodiment of the present disclosure, the BLE communication is used as control communication by which the portable terminal of the transmitter, i.e. an apparatus requesting the connection of the BLE communication, remotely controls the portable terminal of the receiver, i.e. an apparatus receiving and permitting the connection of the BLE communication. Accordingly, in an embodiment of the present disclosure of FIG. 2, the BLE communication of the portable terminal of the transmitter with the portable terminal of the receiver is carried out when the portable terminal of the transmitter requests the portable terminal of the receiver to permit the BLE communication and the portable terminal of the receiver permits the BLE communication.

At this time, the connection of the BLE communication of the portable terminal of the transmitter with the portable terminal of the receiver may be carried out without approval of the user of the portable terminal of the receiver. However, it is assumed that the connection of the BLE communication can be carried out only when the user of the portable terminal of the receiver approves.

In an embodiment of the present disclosure, the apparatus, i.e. the portable terminal of the receiver which is invited for the BLE communication, informs the user of a request of another terminal, i.e. the portable terminal of the transmitter, to connect the BLE communication and requests the user to approve, as indicated by a reference numeral 330 in FIG. 3. Then, the portable terminal of the receiver, i.e. the apparatus invited to connect the BLE communication, connects the BLE communication with the portable terminal of the transmitter according to the user's decision, i.e. an input touch for a menu 331 of menus 331 and 332.

When the BLE communication for the remote control is connected, the portable terminals of the transmitter and the receiver inform each user of the connection of the BLE communication in a form of sound, vibration, or visual information. In an embodiment, the connection of the BLE communication is displayed in a form of visual information through an interface such as an indicator bar (or a quick panel) 341 on a display screen 340, as shown in FIG. 3C. Further, an interface for control of the BLE connection, including menus of disconnect, cancel, reject, filter, and the like may be provided so that the user may set the connected BLE communication.

Alternatively, in an embodiment of the present disclosure, the portable terminal of the transmitter and the portable terminal of the receiver have a white list which is previously stored therein, and selectively perform a series of operations for a connection of the BLE communication through the white list.

The portable terminal, i.e. the portable terminal of the transmitter and the portable terminal of the receiver, according to an embodiment of the present disclosure may use an open address (BD_ADDR) or a MAC Address for a connection of communication with another terminal, i.e. for a connection of the BLE communication as a control communication, but may connect the BLE communication by using the random target address included in the advertising data shown in FIG. 3B. Accordingly, the portable terminals, i.e. the portable terminal of the transmitter and the portable terminal of the receiver, according to an embodiment of the present disclosure can store in advance the white list generated on the basis of the random target address.

For example, the portable terminal of the transmitter previously composes the white list before scanning for the connection of the BLE communication, and identifies the advertising data broadcast by the plurality of apparatuses to ignore the advertising data of the apparatuses which do not correspond to the random target address included in the white list.

Further, the portable terminal of the receiver can ignore a request of an apparatus for the connection of the BLE communication that is not included in the white list. Therefore, it is possible to prevent unnecessary operations of the portable terminal of the transmitter and the portable terminal of the receiver, (for example the operation of the controller), thereby minimizing a consumption of electric current and securing the privacy of the user of the portable terminal.

Alternatively, the apparatus which is managed by using the white list (or the apparatus which is registered in the white list) may be a portable terminal such as a smart phone. However, the apparatus may include service providers to which an address for certification, i.e. random target address, is given. The service providers may include a device service provider, a business service provider, a social service provider, and the like. For example, the random target address is distributed to the service providers which are certified through a certification process, and it makes the BLE connection of the portable terminal, i.e. the portable terminals of the transmitter and the receiver, achievable with the service providers only when the BLE connection is necessary.

An example of the device service provider includes apparatuses of a certain manufacturer, e.g. Samsung Electronics Co. Ltd., using the same protocol, such as a smart phone, a smart TV, a smart appliance and the like. Further, an example of the business service provider includes companies such as Starbucks, SK Energy, Costco, CGV, KORAIL, and the like, which provide commercial services including advertisement, coupons, ordering, ticketing, and the like. Furthermore, an example of the social service provider includes companies such as Facebook, Twitter, Foursquare, and the like, which provide social network services.

Referring back to FIG. 2, at operations S206 to S208 the portable terminal of the transmitter sets up a method of transmitting the content and transmits setting data corresponding to a transmission method which is set to the portable terminal of the receiver. The portable terminal of the receiver changes and applies the setting of the portable terminal in correspondence to the setting data which is received.

When connected to the portable terminal of the receiver to perform the control communication (BLE communication), the portable terminal of the transmitter has to set (select) a communication method to be used for a transmission of the content, i.e. a communication for a transmission of data such as the content.

The portable terminal of the transmitter according to an embodiment of the present disclosure also broadcasts the advertising data by using the BLE module, like the portable terminal of the receiver. It is already described that the advertising data includes information on which wireless communication function a corresponding portable terminal supports by using which protocol, and a current operation mode of the portable terminal.

Accordingly, the portable terminal of the transmitter analyzes the advertising data of the portable terminal of the receiver, and identifies a type of wireless communication function which the portable terminal of the transmitter and the portable terminal of the receiver can utilize in common so as to select a certain wireless communication function.

For example, a wireless communication function having the fastest transmission rate is selected from the wireless communication functions which are utilized in common. For example, when the wireless communication functions of the Bluetooth module (version 3.0 or earlier) and the Wi-Fi module are utilized in common, the Wi-Fi module having a transmission rate relatively faster than the Bluetooth module may be selected.

However, the portable terminal of the transmitter identifies a size property of a content to be transmitted, and selects a wireless communication function from the wireless communication functions which are utilized in common according to the size property. For example, in a case where the wireless communication functions of the Bluetooth module (version 3.0 or earlier) and the Wi-Fi are utilized in common, if the size of the content is smaller than a predetermined size, e.g. 1 Mb, the Bluetooth module (version 3.0 or earlier) having a small latency, i.e. transmission delay rate may be selected. If the size of the content is larger than the threshold size, i.e. 1 Mb, the Wi-Fi module having a rapid transmission rate may be selected. The transmission of the content using the Bluetooth module is disadvantageous in view of the transmission rate, but is advantageous in view of the latency. Therefore, if the size of the content to be transmitted is small, a transmission method using the Bluetooth module is preferable.

When a type of the wireless communication function is selected or determined as described above, the portable terminal of the transmitter identifies whether the selected wireless communication function is activated. If the wireless communication function is not activated, the portable terminal of the transmitter activates the wireless communication function. The portable terminal of the transmitter transmits the setting data shown in FIGS. 3D and 3E to the portable terminal of the receiver by using the connected BLE communication so that the portable terminal of the receiver activates the selected wireless communication function. For example, when the Wi-Fi module is selected and the Wi-Fi module, i.e. the wireless communication function using the Wi-Fi module, is activated in the portable terminal of the transmitter, the portable terminal of the transmitter transmits the setting data so that the Wi-Fi module is activated in the portable terminal of the receiver.

FIGS. 3D and 3E are views illustrating examples of a format of setting data transmitted in the process of transmitting content according to an embodiment of the present disclosure. Referring to FIGS. 3D and 3E, the portable terminal of the transmitter can transmit the setting data to the portable terminal of the receiver in order to control at least one of the wireless communication functions of 01 to 13 and sensors of 14 to 20 in the portable terminal of the receiver, as shown through a category of a bearer and a sensor specific. The portable terminal of the receiver changes its setting based on the received setting data.

For example, when receiving the setting data for turning the Wi-Fi module on from the portable terminal of the transmitter, the portable terminal of the receiver identifies whether the Wi-Fi module thereof is activated. If the Wi-Fi module is activated, the portable terminal of the receiver ignores the setting data. If the Wi-Fi module is not activated, the portable terminal of the receiver activates the Wi-Fi module.

At operations S209 to S211, the portable terminal of the transmitter is connected to the portable terminal of the receiver through the wireless communication by the set transmission method. The content which is requested to be transmitted is transmitted to the portable terminal of the receiver according to the set transmission method. When completing the reception of the content, the portable terminal of the receiver restores the changed setting thereof to the former state.

The portable terminal of the transmitter sets the transmission method in the previous operations and transmits the setting data, which corresponds to the set transmission method, to the portable terminal of the receiver. A series of operations are performed for connecting the communication by the set transmission method, i.e. the selected wireless communication function, which can be automatically performed in the portable terminal of the transmitter.

For example, when the set transmission method is the Bluetooth module (version 3.0 or earlier), and the portable terminals of the transmitter and the receiver are activated, the portable terminal of the transmitter automatically performs a series of processes including a pairing so as to complete the connection with the portable terminal of the receiver by the Bluetooth module (version 3.0 or earlier). As another example, if the set transmission method is the Wi-Fi Direct module, the portable terminals of the transmitter and the receiver automatically perform a series of operations including a device discovery, a service discovery, and a group generation so that the connection of the Wi-Fi Direct module can be achieved between the portable terminals.

When the wireless communication is connected according to the set transmission method, the portable terminal of the transmitter transmits the content which is requested to be transmitted to the portable terminal of the receiver by using the connected wireless communication.

When or after the portable terminal of the transmitter transmits the content, the setting data described with reference to FIGS. 3D and 3E can be transmitted through the BLE which is a control communication. At this time, the transmitted setting data includes a control parameter for controlling the transmitted content. Alternatively, the control parameter may be transmitted at operations S207, and S210, or after operation S210.

Referring to FIGS. 3D and 3E, as shown in categories of music play, remote button, general and apps, the portable terminal of the transmitter transmits the content, and transmits instructions for controlling the transmitted content as the setting data as shown in FIGS. 3D and 3E. For example, the portable terminal can control a reproduction of the transmitted content, e.g. music files, by means of the instructions such as play/pause, next, previous, FF, REW, stop, and the like. As shown through a category of Apps, the portable terminal of the transmitter can transmit instructions for executing a certain application to the portable terminal of the receiver.

When the portable terminal of the transmitter completes the transmission of the content, the portable terminal of the receiver restores the setting, which is changed to receive the content at operation S208, to the former state.

For example, having changed the setting of the portable terminal so that the Wi-Fi module in a state of non-activation is activated to receive the content, the portable terminal of the receiver restores the setting of the portable terminal after completing the reception of the content, so that the Wi-Fi module returns to the initial non-activation state.

Alternatively, in an embodiment of the present disclosure as described above, the portable terminal of the transmitter is connected with the portable terminal of the receiver by the BLE communication for the remote control, selects a type of data communication through the BLE communication, and transmits the content through the connection of the data communication, i.e. a connection of the Wi-Fi.

However, various embodiments of the present disclosure can be applied to a case where the portable terminal of the transmitter is far apart from the portable terminal of the receiver. Although communication using a short-range communication module such as the BLE module and the Wi-Fi module is impossible, the embodiment can be applicable. For example, the portable terminal of the transmitter is connected to the portable terminal of the receiver by way of a relay server, e.g. a cloud server, to perform communication for the remote control and the data transmission, thereby carrying out an embodiment of the present disclosure as described above.

The present disclosure provides an apparatus and method for transmitting content in a portable terminal, which are capable of maximizing usability by simplifying and automating wireless communication functions so that a user can use them conveniently, while minimizing the consumption of electric power which is caused by using the wireless communication functions.
